"NGC 3981 is an unbarred spiral galaxy located 65 million light-years away in the constellation of Crater. It was discovered on February 7, 1785, by William Herschel."(Wikipedia)
"This galaxy features a bright central core, where a supermassive black hole lies, surrounded by a disk of hot, young stars and spiral arms laced with streams of dust and more young stars. The irregular, outstretched shape of its arms is likely due to gravitational influence from an encounter with one of its galactic neighbors. NGC 3981 is a member of the NGC 4038 Group of galaxies, which also contains the well-known interacting Antennae Galaxies. The NGC 4038 Group is a small component of the Virgo Supercluster, the immense collection of galaxies that hosts our own Milky Way Galaxy." (noirlab.edu)
